Either we're screwed, or, I think it's possibly a bug related to your chosen class. On my decker I jammed a bunch of points into pistol to keep up with the fights, after putting a bunch of points into decking, of course. No problem decking, but my pistol skills are not showing up. Started another round of DMS, pistol skills showing up no problem, this time with a Samurai. Also doing Life on a Limb and no problems with my Samurai pistol skills. Any Samurai having this problem with their weapon skills? If so, we'll call it an even bug across the board.

the game does say that these skills are only available with certain weapons and the best version of a type of weapon wont necessarily be able to use all the abilities you get in the relevant karma tree.that said check each abilty to see if it actually says that, the problem is probably a bit of both weapon design and one or two bugs.
